The tour is in support of the Oct. 9 release of Gomez’s “Revival.” “Good for You,” the first single released from the album, peaked at No. 5 on Billboard’s Hot 100 and an even better second single, “Same Old Love,” debuted last week at No. 43.

Gomez has sold more than 22 million singles since launching her singing career as the star of the Disney Channel series, “Wizards of Waverly Place.” As the leader of Selena Gomez & the Scene, she went quadruple-platinum with two Top 40 singles, “Naturally” and the classic “Love You Like a Love Song,” triple-platinum with “Who Says,” double-platinum with “A Year Without Rain” and platinum with “Round & Round” and “Hit the Lights.” Her hits since moving on without the Scene on her first solo album, “Stars Dance,” in 2013 include the triple-platinum “Come & Get It” and the platinum “Slow Down” and “The Heart Wants What It Wants.”
